Man is determined to overcome nature and man-made is to build up the confidence to win when encountering difficulties, strive for success, and give full play to your subjective initiative in order to achieve your own goals and solve current difficulties. This is a sentence that inspires people to work hard in the face of adversity. In reality, it is necessary to build confidence to accomplish something, and it is a prerequisite for success. However, it is up to God to make things happen. Many things are not dependent on human will, and the success of things is far from just that. It can be accomplished by building confidence. While we build confidence, we must also work hard to create conditions for success. The ancients said that the right time, place and people are to create good conditions for success, so that the probability of success will be greater. Farah's first famous quote: Try your best to succeed, but don't expect to succeed. This is what we should do in reality.
